All my cables I would connect to my home PC/macbook are USB C. IE bluetooth adaptor, sd card adaptor, external ssd, mouse/keyboard, a soundbar etc.
I have several chinesium clones of dewalt batteries/tools, IE lights, compressors etc. They all have USB c output.
"most pc perihpials are USB-A" is not exactly correct for some time now. (not that I'm a fan.)
I even bet many mac users wished their device had a usb-a port or two in order to not be so dependent on adapters, hubs and docks.
Lower transfer rate means less shielding is needed for the cable as well as the overmold, and enables longer and more flexible cables, as extra shielding stiffens the cables.
Because they saved die space in silicon? Same reason the MacBook Neo only has a single USB 3 and a USB 2. It seems that their A-series Pro silicon only has hardware for a single USB 3, and their non-Pro silicon doesn't even have it at all. I highly doubt they are sparing pins from the connector, the complexity of making a special port variant for that far surely outweighs any potential savings.
I am semi-frequently annoyed that my laptop has 0 USB-A ports. At least give me one.
The wired controller is USB-A. The bluetooth controllers "are" USB-C... but came with A-to-C cables, not C-to-C.
Approximately every time I want to plug something in to my laptop that's not a charging cable for another device, it's USB-A.
More to the point, anything I'd want to plug in to a gaming machine, is usb a.
Most new gaming mice and keyboards sold in 2026 use USB A. Not to mention all the older ones that still work.
In 2026 the single most useful port to add to my Macs would be USB-A, with no close competition. On any device with 2+ USB-C ports, it'd easily be worth sacrificing a USB-C to get a USB-A.
Most devices have a cable that’s fully replaceable so you can choose to use C to C or C to A but basically everything has usb C on the device end.
Yes, but we're talking about the ports on the Steam Machine, so the host end is what matters. And gaming peripherals are likely even more skewed towards USB A, because Macs are not the main target for that.
The only PC peripheral I have with USB-A is a mouse dongle when I'm lazy and don't connect bluetooth - and that one I connect to the monitor.
All others are usb-c.
Wired Xbox 360 controllers (and most of their off brand alternatives) have a non-removable USB-A cable.
It's a bummer if have none of these cables around, but it's still more elegant than adapting USB3-A stuff to USB-C.
That said I would not trust this as a PSU for a computer which uses almost all the available power output and does not have it's own internal battery. Most USB-C chargers are not designed to run at 100% capacity for extended periods and could not handle sudden spikes over the rated capacity. Even for desktop PSUs you always want to get something that has a good headroom over the actual power draw for stability.
